The answer is geothermal energy. This energy can be harnessed to generate electricity. The energy emanates from the deep core of the earth due to the radioactivity of the rocks in the region. The radioactivity heats Magma from the mantle which subsequently heats the rocks and fluids in the earth crust.
B. None of the others are advantages. But a higher yield would provide more food.

The correct answer is option (a) Scanning tunneling microscope.
Microscopes are used to see the objects at molecular level. Scanning tunneling microscope( STM) is a type of optical microscope that uses optics(light) and lenses to see the enlarged size of the object. This microscope use a small metal tip under a high voltage. when this tip of microscope is brought close to the metal, the metallic tip of microscope draws electrons from the atom (metal) to be observed. This generates an electric current. There is a computer system attached to the microscope that detects the change in the electric current. Computer plots the change in position of atoms in metal.
